14.1.6.2 Density
Density was kriged for each block in the model similarly to grade. There were cases where density was not measured. As a result, there were some gaps in the data. The gaps were assigned values according to their lithology and an analysis to determine average values for each lithological unit. On average, the density value for the F-Zone was 2.95 t/m 3, 2.91 t/m 3 for TZ, and 2.88 t/m 3 for T0.
The density values were considered by the QP to be appropriate for BIC type mineralization.
14.1.6.3 Composite Indicators
The indicators (0 and 1) were composited on a 1 m basis to ensure they had the same support.
14.1.6.4 Create Start Model
After compositing the indicators, an indicator start model was created. This has the same origin as the flattened block model with block sizes of 5 m x 5 m x 1 m in the X, Y, and Z direction, respectively.

14.1.6.5 Setup Indicator Estimation Parameters
The indicator estimation used an inverse distance squared algorithm since the data was already flagged as 0 and 1. The search ellipse was constrained to a single pass.
14.1.6.6 Estimate Indicators
The flagged indicators were estimated using inverse distant weight to obtain a mineralized envelope, as shown in Figure 14-19.
